The Crazy Horse Electric Game by Chris Crutcher

Willie Weaver used to be a hero.
Now he's nothing.

Willie is a top athlete, the star of the legendary game against Crazy Horse Electric. Then a freak accident robs him of his once-amazing physical talents.

Betrayed by his family, his girlfriend, and his own body, Willie's on the run, penniless and terrified on the streets, where he must fight to rebuild both his body and his life.
